NASA has released an amazing image – it's a panorama of 141 wide-angle pictures captured by the Cassini spacecraft on July 19 that gives us one of the most detailed looks yet at the area around Saturn.
As you can see in the image, Earth appears as a bright blue dot on the lower right. Venus is on the upper left. And Mars appears as a faint red dot above and to the left of Venus.
The image covers more than 400,000 miles, which brings us to tonight's number: 746 million miles, which is the distance between Saturn and the Earth when the two planets are at their closest positions. When they're on opposite sides of the Sun, they're more than a billion miles apart!
